Intense pulsed Light ( IPL ) is a technology used by cosmetic and medical practitioners to perform various skincare for aesthetic and therapeutic purposes, including hair removal, photorejuvenation (eg skin pigmentation treatment , sun damage, and yarn veins) and to relieve dermatological diseases such as acne. IPL is increasingly used in optometry and ophthalmology as well, to treat dry eye diseases evaporating due to meibom gland dysfunction.
This technology uses high-powered, hand-held, computer-controlled flashguns to produce strong, visible, wide-spectrum light pulses, generally in the visible spectrum range from 400 to 1200Ã, nm. Various filter cutoffs are commonly used to selectively filter out lower waves, especially potentially damaging ultra violet light. The resulting light has a spectral range that targets specific structures and chromophores (eg, melanin in hair, or oxyhemoglobin in a vein) that is heated to the point of being destroyed and reabsorbed by the body. IPL shares some similarities with laser treatments, since both use light to heat and destroy their targets. But unlike lasers that use a single wavelength (color) of light that usually only fits with one chromophore, and hence only one condition, IPL uses a wide spectrum which, when used with a filter, allows it to be used against several conditions. This can be achieved when an IPL technician selects an appropriate filter that fits a particular chromophore.

Description
Intense pulsed Light is the use of intense non-coherent light pulses in the wavelength range from 500 nm to 1200 nm. Xenon flashlamps produce high-output broad spectral outbursts. Cooling is used to protect the skin that comes into contact with the device.
The rules governing IPL vary by jurisdiction. "Intense Pulsed Light" is not a registered trademark. Differences are sometimes made between beauty class machines and medical classes, especially for regulatory arrangements. Under the CE marking system there is no such distinction.
The first FDA approval from IPL was for telangiectasias in 1995. Use rapid spreads to various medical settings and cosmetics. Treatment is generally safe and effective, but complications can occur such as hyperpigmentation. Polychromatic light can reach several chromophores in human skin: mainly hemoglobin, water, and melanin. This produces a selective photothermolysis of the target, which can be blood vessels, pigmented cells, or hair follicles.

Hair removal
IPL can permanently reduce hair growth, most effective in darker and coarser hair. There are many names and devices for pulsed light treatments such as E-Light, ELOS, and M-Light. Laser hair removal is different and uses coherent, monochromatic laser light.
Protocol
Broad-spectrum light is applied to the skin surface, targeting melanin. This light travels through the skin until it grabs the hair shaft or bulb (root). The bulb is usually where the highest concentration of melanin is located. When light is absorbed, the bulb and most of the hair rods are heated, destroying the hair-producing papilla. It also claims that the conversion of heat occurs directly in the dark capillaries that carry blood to the follicles.
At one time, not all hair follicles were 'active', and only active hair follicles could be affected by treatment. Hair follicles that are 'inactive' can be treated because they become 'active' from time to time. For IPL treatment, an average of 8-10 treatments is needed to remove most of the visible hair. There is no general treatment protocol and it depends on the equipment used and the skin type of the patient. The treated area should be clean and sun-free. Treatment sessions are usually 4 to 6 weeks apart. Treatment is often given in the doctor's office and so-called "medspas" by a trained practitioner.
Contrary to what is often claimed, photoepilation is not a permanent hair removal method but a permanent hair reduction method. Although IPL treatment will permanently reduce the total amount of body hair, they will not result in permanent removal of all hair. This difference is only relevant in the US because of the FDA's words.
Certain skin conditions, health irregularities, and medications can have an impact on whether it is safe for someone to receive light-based hair removal treatment. Photo sensitization drugs, or damage to the skin are contraindicated for treatment. According to Remington, the manufacturer of IPL devices, all IPL and laser devices should only be used on light to medium tones, and work best on darker hair.
Benefits
The first use of specific IPL systems developed for hair removal was reported in the literature in 1997. The decrease in hair counts was found to be ~ 60% (12 weeks), 75% (1 year), 60% (2 years). Various treatment protocols have been studied.
It is important to note that this study uses various IPL devices in different areas of the skin, and uses patients with different types of hair and skin. Thus the results can not be compared directly. In evaluating these results it is also important to remember that even a 75% reduction indicates that 25% of hair regrets after treatment. The permanent hair removal in this study, as defined by the FDA, means "long-term stable reduction in the amount of hair regrowth after the treatment regime". The amount of hair that regenerates must be stable over time, greater than the duration of the hair follicle growth cycle, which varies from four to twelve months based on the location of the body. There is no treatment to date that demonstrates the ability to permanently remove all hair growth, but many patients experience satisfaction with significant and permanent reductions.
A 2006 article in the journal "Lasers in Medical Sciences" compares IPL and laser alexandrite and diodes. This review found no statistical difference in its effectiveness, but a higher incidence of adverse events with laser diode treatments. Hair reduction after 6 months was reported as 68.75% for alexandrite lasers, 71.71% for laser diodes, and 66.96% for IPL. Adverse reactions were reported as 9.5% for alexandrite lasers, 28.9% for laser diodes, and 15.3% for IPL. All side effects are found temporarily and even pigmentation changes return to normal within 6 months.
Medical use
IPL was first developed for vascular conditions. This is at least as effective as pulsed dye lasers and can penetrate deeper by reducing the risk of purpura and hyperpigmentation. IPL can also be used for the treatment of dry eye conditions such as meibom gland dysfunction. IPL can treat pigmented lesions with rapid recovery. Dyschromia can be cleaned after recurring sessions. Photoaging care has been explored. A series of IPL can be used for facial rejuvenation, improve skin weakness and collagen production. IPL combined with facial injections can be used for dynamic rhytids. Home IPL devices have been developed.
BBL (Broadband Light), developed by US-based Sciton. is an advanced version of IPL technology in recorded light therapy that has set a higher standard for treating skin conditions associated with aging, pigmentation irregularities and removal of hair follicles. The difference between IPL and BBL basically goes down to operation at different wavelengths. With advances in research, light science and technology, BBL provides more accurate parameters to deliver more targeted and superior results than its IPL partners. Extensive research and research have proven that regular BBL treatment not only prevents cell aging, but also turns back the clock, causing the expression of DNA of skin cells to return to a healthy and healthy state.
IPL is used in the treatment of various dermatological conditions including photodamage induced dyspigmentation and vascular changes, poicyloderma from Civatte, rosacea, acne vulgaris, sebaceous gland hyperplasia, defective capillaries/telangiectasis, vascular lesions, freckles, liver, birthmark), melasma, actinic keratosis, photorejuvenation, basal cell carcinoma, and Bowen's disease (squamous cell carcinoma).
